Math Links for Week Ending Feb. 28th, 2020

If you follow this blog at all then you know that it's all about sharing stuff. Specifically stuff that I find in the Internet world. However, I'm sure that even though I really try to never show the same link twice, that often I probably share stuff from some of the same sources. So that's why I like finding other people that share stuff that they find (and you should too). This week it's @HTheijsmeijer. She has started a blog to share the stuff that she has found. So check it out.

A new @Desmos activity gives a nice introduction into the idea of what a function is. One of the interesting representations on this one is where they using words in the function machine. Check it out.

For years on the @Desmos homepage, there have been links to sample images created with the Graphing Calculator. So, to me, it seems surprising that it has taken this long for them to have a formal contest. So here it is, the first Desmos Art Contest. Students can win cash prizes in each of the age groups. Due date is April 10th. Get all the details at the link below

This is an activity we created to help develop the idea that the volume of a right prism is equal to the area of the base times the height. It's relatively simple as it just uses snap cubes and a grid handout. There is also some practice via paper & pencil or @Desmos.

I've also had a couple of other @Desmos activities for multiplying and dividing decimals that focus on some of the properties of those operations. Like for multiplication of values with the same sets of digits (eg 4.5x3.4 and 0.45x3.4) the numerical values are the same but the decimal place changes and similar properties for dividing decimals. These are not activities for determining how to multiply or divide decimals but instead, what are the consequences of doing so.

Do you want to know how geometry relates to arithmetic or probability to calculus? Then why not check out this interactive Map of Mathematics from @QuantaMagazine. The interface is pretty slick. Just choose a topic and see the "tentacles" dynamically reach out to all the related topics. There are some very cool animations here and definitely some great information. Check it out.

This is the last of three bonus episodes highlighting all the featured speakers from OAME 2020. This time its just a few minutes from each as they answer the question: " Is there anything that you believed to be true about teaching or learning when you began your career that you no longer do?". It was one of my favourite episodes to record and I loved the responses. Have a listen

I've always been a big fan of Geometer's Sketchpad. In recent years, it has bounced around different companies as things were bought out from other things. But thanks to a small team of dedicated people, it continues to live on and get better. If you are interested in beta testing the latest version then you can contact Daniel Scher. And if you are looking for some web sketches created with Sketchpad, check out the link for all of mine.

We released two episodes of OAME talks within the last week. The first was our normal monthly episode featuring @AlexOverwijk and @PaiMath. They were talking about their upcoming webinar "Manage Flow and Let Go!" about some of the logistics of the Thinking Classroom. The second episode is a bonus episode that highlights the featured speakers on day 1 of OAME 2020 in May. That's @Drvcjones, @MaryBourassa, Ian VanderBurgh, @ddmeyer & @Marian_Small all talking about their featured talk. Check both episodes out below.

I created two related @desmos activities about multiplication. The first is one is for students to investigate the idea of multiplying two digit numbers by using an area model and to eventually take a question like 48x62 and essentially multiply (40 + 8)x(60x2) instead. The second one expands on this idea to model a single decimal number by another single decimal number. First in the form 1.3x1.8 and then moving to questions like 3.5x7.2. Both have random problem generators.

It's no secret that I love @Desmos. You might too and so you should apply to be a Desmos Fellow. It's a great way to deepen your Desmos knowledge and become part of a group fo educators who are trying to use technology to enhance teaching.
